Comment:

 Ok -- I have 4 patches that fix this up so that we DTRT. There are still 2
 UI glitches

  - 0001-Removable-disk-Save-metadata-and-preview-dlo-9657.patch
  - 0002-Removable-disk-read-json-formatted-.metadata-and-.pr.patch
  - 0003-Removable-disk-Handle-renames-dlo-9657.patch
  - 0004-Removable-disk-delete-preview-and-metadata-dlo-9657.patch

 With this

  - We save the files with their correct metadata
  - Read the metadata back, display it, copy it correctly into the DS, and
 search descriptions/tags if the user runs a search
  - Renames and removes are handled correctly on-disk (metadata/preview
 files are renamed or removed

 The results are not perfect, as we have UI glitches -- on delete the file
 listing doesn't remove the file 'collapsedentry'; on rename, the new name
 is shown until you touch the scrollbar.

 To fix those UI glitches we need to issue a message to the
 InplaceResultSet instance somehow... except that we don't have a handle to
 it. I also attempted to do something like
 http://git.sugarlabs.org/projects/sugar/repos/mainline/commits/b0113bf67c31dbeaa08cf0f1710c1be8d02a9b25
 which sure looks right, but didn't work for me.

 Triggering these actions from the UI widget objects makes it all overly
 confusing to a newcomer like me. The ocassional dbus message makes it even
 more entertaining.

 In any case, the patches bring the backend behaviour to correctness. With
 some help we can also address the UI glitches (or punt and deal with them
 with later).
